Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Hybrid Decision Support System for Predicting and Managing of Cognitive Styles Changes A.S. KRIVENKOV, V.M. TYUTYUNNIK The main modern publications on data-based, model-based, and knowledge-based decision support systems (DSS) have been analyzed. Three requirements and six levels with sublevels of a reference architecture of a hybrid DSS for predicting and managing cognitive learning styles have been formulated. Such a hybrid DSS implements a closed loop: data → analytics → inter-vention → evaluation → adjustment. The main features of the functioning of a hybrid DSS in the conditions of learning analytics and educational data mining have been identified and described. Keywords: hybrid decision support system, forecasting, management, and cognitive style dynamics. DOI: 10.25791/pribor.4.2026.1665 Pp. 26-30.
